Heidi Klum, Queen of Halloween, drops another hint for this year's 'bloody' costume

The Queen of Halloween is back! Supermodel Heidi Klum, known for her grotesque, over-the-top Halloween looks, took to Instagram on Wednesday to share another sneak peek of this year's costume.

Klum shared a video of prosthetics that appeared to resemble fungus.

"Have u figured it out yet?? Only time will tell 🤫 3 more days…," Klum captioned the clip.

Fans have continued flooding Klum's comments with guesses, including Monstro Elisasue from The Substance , a Clicker from The Last of Us , Vecna from Stranger Things and a monster from Resident Evil.

Klum's longtime collaborator, special effects makeup artist Mike Marino, previously dropped a hint of his own. While chatting with NBC's Hollywood ReelTime , Marino revealed that Klum's look this year is "one of the most elaborate costumes ever made."

"It's so difficult to do and just the complication of it is really challenging," Marino said. "It might not appear to some people sometimes how much work goes into it but there's so much that goes into these things."

The supermodel shared another hint on Tuesday, with an image of even more prosthetics.

"4 more days," Klum wrote, alongside a series of spooky emoji. "#HeidiHalloween."

Klum initially teased this year's gruesome creation on Oct. 24, sharing a close-up on Instagram.

The mysterious image appears to show an array of prosthetics resembling human organs. Klum's fans were quick to share their predictions for her costume. Guesses ranged from short and sweet to hyper-specific, from "Coral reef. Inspired by St. Barth's" to "pirates of the caribbean when the pirates become sea creatures on the flying dutchman."

"Internal organs?" one commenter asked, while another remarked, "Looks like the inside of a stomach."

"Idk but I'm gagging already," admitted another fan.

Klum has been sparing with her hints. Aside from the graphic, organ-like prosthetics, the supermodel told Parade that this year's costume will be "bloody."

It looks like we'll have to wait a few more days for Klum's final look. Each year, Klum unveils her full costume at her star-studded costume party on Oct. 31 in New York City. This year marks her 25th annual Halloween bash.

When it comes to her costume for All Hallows' Eve, Klum has a history of going all-out . Over the years, Klum has consistently debuted high-concept, unsightly transformations. Her greatest hits include E.T., a gigantic peacock, a slinky worm, a skin-baring zombie creature and Fiona from Shrek . Last year, Klum slithered into her costume bash as Medusa, complete with a scaled body, a tail and a head of snakes. Klum's husband, Tom Kaulitz, is always game to help bring her vision to life too, whether he's dressed as the Greek soldier that Medusa turned to stone, a bloodied fisherman or the Shrek to her Fiona.

Klum opened up about what sparked her desire to throw a costume party every Halloween, telling Parade, "I'd go to some of these Halloween parties and people were just not given anything."

Klum isn't concerned with looking sexy on Halloween. In fact, she prefers to go in the complete opposite direction. After seeing one too many unimpressive costumes, she decided to take matters into her own hands, hosting her first Halloween party in 2000.

"This is really how it sparked my idea on doing one myself because I thought all the parties were so lame and the costumes people were doing even lamer," Klum told Parade. "I was like, 'There needs to be a person who really shows them to give more.'"
